Title:
  do-release-upgrade broked WSL

Status in bash package in Ubuntu:
  New

Bug description:
  I had Ubuntu 17.04 installed in WSL and decided to upgrade it to
  17.10, so I had run do-release-upgrade, as I did before to upgrade to
  17.04. Everything was fine before script started upgrading packages.
  It's started from bash updating, and somehow there is a problem
  revealed that locale files is missing, and locale-gen can't be run
  (because of bug in WSL). I've tried to install language-pack-en as was
  suggested, but problem haven't resolved, any attempt to update leads
  to this error.
